Don't show dashed outline on empty instances permanently

[kof]

In some cases like this one, with Navigation Menu, Viewport Container is going to stay without content that can inflate it's size, so we are keeping the size at a minimum and showing the dashed outline, but in this case its not necessary because this item won't have any other content and so these dashes are annoying.

We can introduce some additional logic that checks if any of the parents within that component, e.g. Navigation Menu are selected and if not, don't inflate and hide the outlines.

Another option is to do it like webflow with a direct setting for this: "show empty elements"
